I want to create a GET action addition the existing GET in different signature how could I do it?

See more:

WebAPI

//This is the First GET action that works excellent!
public string Get(string carrier, int flightNum, DateTime date, string acNum)


//This is the second GET action
public void Get(string isaData)
{
}



//and in the JS I send in in AJAX(for the second GET action) it doesn't work WHY???:

$(document).on("click", "#save-button", function () {
$.ajax({
url: WebApiUrl + 'Isa',
data: localStorage.getItem("data"),
type: 'GET',
contentType: 'text/plain',

});
});
